Prior to the firmware upgrade I had connectivity, just the performance didn’t seem right. After the upgrade there is no connectivity at all and the device is stuck in “+CFUN: 5”.
This is the end of the firehose log that I posted earlier:

For me this looks like the update was finished. The modem was sent a reset command. after the reset command firehose tried to send something additionally, but since the modem was resetting it didn’t get the last command.
This is why I assume that the modem just hasn’t received the last “get out of CFUN: 5” command.
But these are just assumptions.
The commands that you sent were working before the firmware update, they did not return ERROR. Just no 5G connection was established. But for now, I just want to recover the modem and will test once more if I can get 5G from a location where it was more performant last time I tested another module.
